There is a clear cut way to do it on the Xbox 360 but unfortunately it is broke and refuses to connect to the WiFi. Is there a way to change your Microsoft account on the Xbox One? Long story short I need to release my dads email (was used so he could pay for the Gold) so he can make a new Gamertag for it and then attach my email to the existing profile, but I dont see any option to mess with your email at all on the One. Reason for this is that we've run into a problem with most games on the One being a single save file only, unlike the 360. He would just made a new save file or played a game I didn't want to play. We got Need For Speed Rivals and even though it was his birthday gift he can't play it because then I wouldn't be able to. So it kinda sucks for him that he has to sit there watching me play his game.
I heard about changing your alias on your live account. Would that work with two different people? If someone could walk me through how that would be possible with my situation please go ahead.
If all else fails then we'll have to get a new 360 and have to wait the 30 days after signing in :/
